The rich inner life of the cell nucleus: dynamic organization, active flows, and emergent rheology
A Zidovska - Biophysical Reviews, 2020 - Springer
The cell nucleus stores the genetic material essential for life, and provides the environment
for transcription, maintenance, and replication of the genome. Moreover, the nucleoplasm is …

Euchromatin activity enhances segregation and compaction of heterochromatin in the cell nucleus
The large-scale organization of the genome inside the cell nucleus is critical for the cell's
function. Chromatin—the functional form of DNA in cells—serves as a template for active …

Interphase chromatin undergoes a local sol-gel transition upon cell differentiation
Cell differentiation, the process by which stem cells become specialized cells, is associated
with chromatin reorganization inside the cell nucleus. Here, we measure the chromatin …

Activity-driven phase transition causes coherent flows of chromatin
We discover a new type of nonequilibrium phase transition in a model of chromatin
dynamics, which accounts for the coherent motions that have been observed in experiment …

The power of weak, transient interactions across biology: A paradigm of emergent behavior
A growing list of diverse biological systems and their equally diverse functionalities provides
realizations of a paradigm of emergent behavior. In each of these biological systems …

Dynamical phase transition in models that couple chromatin folding with histone modifications
Genomic regions can acquire heritable epigenetic states through unique histone
modifications, which lead to stable gene expression patterns without altering the underlying …
